ACCOUNT ATTACHMENT FOR CASH-REGISTERS.

Specification of Letters Patent.

Patented Feb. 11, 1913.

Application filed March 25, 1910. Serial No. 551,498.

To all whom it may concern:

Be it known that I, BYRON Buss VVELLs, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Account At tachments for CasliRegisters,- of which the following is a specification.

This invention relates to an account file attachment foi cash registers, and particularly to a device which employs a series of files or receptacles within whichflmay be kept accounts against different customers.

An object of the invention is to provide means whereby, whenever a file or receptacle is drawn out, its return to closed position is prevented until after an operation of the cash register, so as to insure the proper registration of the item which has been entered upon the account slip in the receptacle.

A further object of the invention is to provide means whereby another operation of the cash register is prevented until the files or receptacles have been all locked against return movement.

A further object of the invention is to provide means whereby access to the. receptacle is prevented until the same has been drawn out..to the full limit of its openposition.

A further object of the invention is to provide means. for exposing the balance of any account in any receptacle without the necessity of completely withdrawing the same from its cabinet, but at the same time prevent any access" to said receptacle.

A further object of theinvention is to provide means whereby, upon the partial withdrawal of any receptacle, the interlocking mechanism remains in inoperative position so as to obviate the necessity of an operation of the cash. register so that the file or receptacle may be again returned to.

its normal closed position without the requirement of an operation of 'said cash register.

A further object of-the invention is to provide means whereby the removal of an account on file in any receptacle is prevented until said receptacles have been with drawn to complete open vposition.

A further object of my invention is'to provide means for locking the receptacle against return movement until certain special keys upon the cash register have been operated, such as keys representing ,7 i h )7 Charge Received. on account and Return A further object of my invention is to provide means for permitting the return of any file or receptacle withouta registration of an amount upon the cashregister in the event that the wrong till has been with tions and combinations of parts hereinafter described and set forth in the claims.

Fig. 16'is also an end elevation of the cash register similar to Fig. 13 but havingso'me of the frame and operating parts broken away. Fig; 17 is a detail of one of the plates for operating the retaining device forthe register pawls. I

Like parts are represented by similar characters of reference in the several views. The cash register to, whichl have shown my improvements applied is a register of the .well known drawenoperated type, although the invention is applicable to and each of the covers has secured thereto on op-' posite sides thereof near its rear end a bearing-seat a, open at the top. Projecting rearwardly from the receptacle proper adjacent each of these hearings is a, perforated ear or lug, a and extending through these perforated ears or lugs with its ends resting in the open bearings a is ahinge-rod a.

Coiled about this rod a adjacent each one] of the ears 0. is a spring a? withone of its ends confined ,by a projection a on the rear end of the cover and its other end projecting against the lower edge of the rear end -of the receptacle so as to normally hold said receptacle in raised position against the cover. Each of the receptacles is somewhat shorter than its cover so-that after the same has been drawn out until its rear eiid clears the cabi net, the operator may, by pressing-down on thereceptacle, expose the accounts therein, as shown at the right of Figl If desired, the receptacle may be completely removed from the cabinet after it has. been drawn out to the full limit of its'mov'ement by lifting up on the rear end of the same so as to remay be attached to any other type of regismove the ends. .of the rod a from theopen. bearings a projections a. which extend over the rear arms of the springs serving to maintain said springs in positionafter the re ceptacle is removed, and said springs being 1 bent down at their rear ends as shown'at a so that when thereceptacle is again placed in position the rear ends of. thesesprings will clear the projections a 0n the cover; Each of the covers is, cutaway at itsforward right handjcorner as 'shown at 09-50 as to expose the balance of the account contained inthereceptacle.

receptacleskmay be drawn out at any time for the purpose of access to the account slips therein, but, before said receptacle may' be Locking devices for the receptaclea-The' again returned to itsclosed'positionwithin the cabinet, means are provided whereby anoperation of the cash register must firstv be performed so as to insure the amount of the.

item entered on the account being also reg- 'istered upon the cash register. In order to accomplish'this, I have provided locking de-. vices by which in the normal condition of the machine all of the receptacles are locked against return movement, but which, as soon as the cash registerisoperated, will permit drawn out; or, in case two or more receptacles'have been drla'wn out,"will permit the return of one ofsaidreceptacles but;.will

lock theiother receptacle fromreti'irninovement until after the"nextfsuc'ceeding operation of the cash register.

of receptacles-isa series of pivoted ar'ins b,

pivoted at their rear ends to any suitable point ofthe cabinet as'indijcated-at b. .The

. the return of. the receptacle which has been t.

one for each receptacle, these arms-being forward ends of these arms are "provided,

with projections '6 which in the normal condition of the device rest up'oneachother as shown in'Fig;.5; this construction leaving an open space between the respective arms for. the purpose hereinafterreferred -w. Movably mounted upon each of the pivoted arms is a 'plate bieach of said plates having at its front and rear an inclined 'slot 6,

which slots terminate at their upper-ends in horizontal slotted portions, b Pins, I), extend laterally from the pivoted arms through these slots and springs b secured at one end to the pivoted arms and at the other end to the forward portion of the plates,

tend normally to pull said plates to a posi- I tion where the pins will be located in the short horizontal portion in which positioii the beveled forward portions, 1), of said plates will extend below the lower portions of the respective-arms.

Located on the side of each receptacle cover'near its rear end is a laterally pro jecting drawn out, engages the under side of the pin 1)", which when the receptacle is 100 1 Located at the'side of eachvertical series j plate 6 corresponding thereto and raises said plate from its path of movement, the under side of said plate being inclined upwardly toward the rear to permit said pin to passqbeneat-h the rear end of same. As

soon as said pin has passed beyond the forthe tendency will be forthe projection there-i unlocked by the proper operation of the cash register, to separate and permit the swinging arms of any one series to move upwardly; the adjacent ends of said blocks,

0, being provided With beveled surfaces 0 and the top edge of the extreme upper arm I) of each series being likewise beveled as indicated at c to cobperate with the beveled portions of said blocks so that said blocks will be forced apart to permit of the upward movement of said arms; It may be stated at this point, however, that when one arm is moved upwardly between said blocks it will lock the other blocks against movement and thus cause them to form a bar against the movement of any of the other arms of any other series.

Connected to tlieouter end of the last one of the series of said locking blocks, a, by a bell crank lever d is a rod (1, a guide d serving to confine sa'id rod more or less to a vertical position but permitting it to swing slightly for the purpose hereinafter described. The outer locking block, 0, is provided with a' slot 0 through which ex tends a guide pin a to cause said block to move in a horizontalcdirection when opcrated by the rod and bell ,crank described. This bell crank and guide rod of may be supported upon a suitable bracket, 0?, attached to the register frame. The lower'end of the rod, (1, has a laterally projectipg pin (Z? adapted to nori'ually rest upon a'stationary portion (1* and thus lock said rod d from downward movement and consequentl lock the blocks 1; and through them the swinging arms I), which is the normal conditibn' of the various parts.

Pivoted to a laterally-projecting arm d on said locking rod, d, is a plate d which has a series of iiiclined slots d which lie in the path 'of movement of laterally projecting pins d 'on certain of the keys cl a1 and cl of the cash register; these keys in the present instance being, respectively, certain of the department keys marked Re turn, Charge and Received on account. The lower end of this pivoted plate d? has a projection 03 which, when any one of said keys is depressed, will be brought into the path of movement of a projection d on a moving part of the cash register, which in the present case is a swinging yoke (i common to a register of this type; this yoke being what is known asthe 'main yoke and which, when 'the cash drawer is opened, swings down by gravity or otherwise, and is returned to its normal position by said cash drawer for the purpose of operating the registering wheels and other devices. As'soon as the projection d strikes the projection al the locking rod. will be swung forwardly 'so as to free the projecting pin d thereon from the stop d. 'It will be seen now that the locking blocks 0 and swinging locking arms I) will be unlocked so as to permit the return of any receptacle which has been drawn out. .Means are provided for causing said locking rod, d, to again assume its locked position just as soon as the receptacle which is being pushed in has neared the limit of its inward-movement; Located on the said locking rod, (1, is a beveled projection (Z and located in a stationary part of the frame 'is a plunger d normally spring pressed by a spring d into the path of movement of said beveledprojection d9. Also located on said rod', d, is a pin (1", which when said rod d is in locked'position, lies on one side of a stationary block d", as shown in Fig. 7. It will be seen now that as the receptacle is pushed inthe projecting pin 6 thereon will, by contact with the forward end of the plate 'b corresponding thereto, force all of the swinging arms above it upwardly and thus cause one or more of the locking blocks 0 to move longitudinally,

which movement of the locking blocks will,

the pin has passed from under the block (l a spring d secured to the bracket 0 and also to said rod, will draw said rod upwardly, and, as soon as the pi d has passed above the said block (l".=th,e spring z! of said pawl and the spring d will swing the rod, d, over until the pin (i on said rod again rests on top of the stationary projection d" and again locks said rod a; ainst movement, a stop (I limiting the ntovement of the pawl. At this point of the operation, however, the rod will not be swung to its complete normal locked position, by reason ofthe fact that the projec- ,tion of will strike against the side of the projection d, but just as soonaas the cash.- drawer is closed and the yoke J? and operatedkey returned to normal position the rod will swing to its normalposition' so as to bring the projection d lnffiin with the projection d and the plate, d will also swing back to its normal position soas to remove the rojection d fro'rn the path of movement 0 n the projectio .until a key 03 d or d has been again :pperated and by reason ofthe pawld, any return movement .of the lockingrod, d, is prevented during the time its spring is drawing it up to'locking position, as in case where another rece tacle was attempted t b pushed'in in a manner which will more-fully hereinaft I It has been seen that as long as the projection b on the receptacle is-ipassin g' under its plate b upon the return movement of the receptacle, the swinging arms above it have been forced UPSQfiS to form a bar to the movement of any'of the blocks 0, so that'the swinging arms, of the other series of receptacles will bello'cked. It will further be seen that so long asthe projection b is holding the swingingiarms, I) up the locking rod 0! is being heldjdown out of locking position and the iswinging arms must first be released by the 1feceptacle projection before the rod 0! can be'brought back'to locking position. It

will thus'ibeseen that there is a brief intervalv during the return movement of any recep em-1e wherein all the other'receptacls will series of pivoted arms I) is a plate 0, all of said plates being connected together by a rod 6 which extends under the receptacles. Each of the plates, 6, has a series of laterally projectingflanges e inclined at each end, lying the path of movement of the respective I receptacle projection b so that as a receptacle-ls pushed in the plates e, will be moved l bodily upwardly at-a certain point in the .movement ofthe receptacle so as to bring ,Q-{e rplained a little beveled projections e on the forward edges thereof into the path of movement of the projectionb? ofany other receptacle which may havgbeen drawn out, in any of the seriesoff reeeptacles' These beveled projections" eextend-out just far enough, when the plate-alias been raised up in the manner described, to,prevent the projection 12 on any'other receptacle from coming in contact with "thebeiieled forward edge of its correspondingiiplate or, in the event that a second receptacle has been pushed up into contact with its plate I) justafter the first receptacle has been started in, so soon as the plates 6 havebeen raised up by the contact of the receptacle projection b of the first receptacle with one of the flanges .e, the beveled projection e thereon will force the outer receptacle rojection b awayfrom its plate I) and hol -it away until the lockin rod, d has reached its locking position.

' It will be. seen that the top edge of each of the swinging arms b, lies just below, in

its normal position, the pin 1) of the receptacle which is located just above it, sothat as any receptacle is bein pushed in its pin b? will form a lock against upward move- "ment of all of the swinging-arms of'that series which are located below it and conse quently all the lower receptacles will be locked. Each one of the swinging arms has on the upper forward edge thereof a recess I) so that in case two or more receptacles in the same series have been drawn out to the full limit, a lower receptacle may be again pushed in; these recesses being located at points which will be in line with the reoeptacle projections b of the open receptacle so that said projections will form no bar to any upward movement of said arms.

Means are provided for throwing the locking devices for the reoeptacleout of operation so as to permit the return of any one of the receptacles at any time without respect to the operation of the cash register, this lock-releasing means being adapted to be operated by a special key which may be retained in the possession of the proprietor. Extending above the series of locking blocks 0 and parallel therewith, is a retaining strip 7 which confines said locking blocks from upward movement. This strip is itself re tained against upward movement by the pins f which extend from any suitable point from the cabinet over projections f on said strip. I

f represents a lock of any ordinary construction, located in the front wall of the cabinet. The bolt f of this look has a laterally projecting pin f which extends into an inclined slotted opening f in saidstrip f. By operating the lock so as to project the bolt f, the pin f operating in the slotted opening will cause the retaining strip f to he slid to the dotted line position of Fig. 1

so as to brin the projections f from under the pins f a ter which the strip f, and consequently the blocks 0, will be permitted to yield upwardly and thus form no obstruction to the upward movement of any of the swinging arms I); the vertical portion f of said slot f permitting of a limited upward movement of the strip f.

It may sometimes happen that the wrong receptacle is drawn out by the operator. In such cases the operator, by operating the key marked Return represented by d and opening the cash drawer may unlock the vertical rod d and thus permit the wrong receptacle to be again returned to its closed position within the cabinet. The return of this receptacle, of course, causes the rod (Z to again assume its locking position in the manner before described. This return key (Z corresponds to the usual no sale key and its operation does not affect the registering mechanism; by reason of the fact that its depression does not operate either one of the plates or hereinafter described and consequently will not release the registering pawls of either series of wheels.

In the machine which I have shown in the drawings I have illustrated two sets of registering wheels, one set bein for cash items and the other for charge items. I have further provided means whereby upon the pressing in of the charge department key, the operating devices for the cash registering wheels will be retained against move ment, and, likewise, whenever a cash transaction is made upon the machine, the operating devices for the charge registering wheels will be held against movement. As is common in cash registers oi" the type illustrated, there is provided a series of pawls g, for the cash registering wheels 5 and a series of pawls g for the charge registering wheels, hen the cash drawer of the machine is opened and the main yoke (17 drops, the pawls of the respective registering wheels corresponding to the cash keys which have been operated will also drop until arrested by the operated keys. Vhen the drawer is again closed the frames on the main yoke will force these pawls into engagement with the registering wheels and return them back to their normal position, at the same time moving the registering wheels. a distance corresponding to the operated keys.

Pivoted at the side of the charge (0P received on account (J and cash (a keys are two plates 9' and g. The plate 9 is adapted to be engaged by later ally projecting pins, 9 on the respective received cn account and cash keys (Z and d when the same are operated, and through the medium of the link will rock the shaft g whichis journaled in the frame of the "cash register and extends above the series of registering pawls. This shaft 9' has an arm g which carries a laterally projecting finger g which finger normally extends under a series of hooks g of the cash registering pawls, g. The plate 9 is cut away as shown at g" so as to be out of the path of movement of the pins 9 but has a projection 9 lying in the path of movement of a pin 9 on the charge 'key 01 so that when said charge key is operated said plate will, through the medium of a link 9 rock a loose sleeve 9 on said shaft 9 this sleeve 9 likewise having an arm y which carries a laterally projecting finger g which normally lies under a series of hooks g on the registering pawls for the charge registering wheels. It will thus be seen that when the charge key is depressed the registering pawls for the cash registering wheels will remain in locked condition, and vice versa when the Re ceived on account or Cash keys are de pressed.

It will be seen thatthe lower end of the rod d, when said rod is in locked position stands just above the top of the cash drawer so that when a till is pushed in and the rod (1 forced downwardly in the manner before described, the lower end of the rod will come into the path of movement of the cash drawer and thus prevent the cash'drawer from being returned to its closed position until said rod is again returned to its locked position and the receptacles thus locked against return movement.
